3. Read memory location
The „read“ option applies to any memory location provided with a line number in the programming chart (except
for the separating lines marked by dashes).
Protocol: <STX> identifier line <ETX> [<CR>] can be applied to any line.
The tachometer reply however may differ in length of the protocol from line to line since it depends on the data
volume of the respective memory location.
TA134 enables reading both in RUN and PGM mode. The only difference is in the tacho reply marked by „R“ or
„P“ according to the corresponding operating mode as described in the following example:
Reply to a Read command (standard)
<STX> identifier line mode data <ETX> <CR>
Mode
P=TA134 is in PGM mode
R=TA134 is in RUN mode
Data max. digit number, with preceding zeroes w/o decimal point
(exception: lines 4 and 7 – with decimal point)
3.1. Example for reading memory locations
The parameters below apply to the following examples:
Identifier = 35; tacho operating mode = R (RUN)
Read actual tachometer value (line=01, value displayed =1500)
Request: <STX>3501<ETX>
Reply: <STX>3501R001500<ETX><CR>
Read scaling factor SF (line=07, parameter =1,0000)
Request: <STX>3507<ETX>
Reply: <STX>3507R01.0000<ETX><CR>
Read standard display (line=27, parameter =Pos. 2)
Request: <STX>3527<ETX>
Reply: <STX>3527R2<ETX><CR> (2 meaning: P2 limit)
Read device identifier (line=54, device identifier=35)
Request: <STX>3554<ETX>
Reply: <STX>3554R35<ETX><CR>
4. Writing memory locations
The „write“ option applies to any memory location provided with a line number in the programming chart except
for the separating lines (marked by dashes) and lines 1 and 6.
Protocol: <STX> identifier line P data <ETX> [<CR>] can be applied to any line.
The reply given by the tachometer after each individual parameter poll is the same as for a read command in the
respective line.
Programming of memory locations both in RUN and PGM mode.
Programming in RUN mode:
The parameters in lines 28, 29, 31-33, 35, 49 and 51-54 are only retained after having switched from PGM
mode to RUN mode. For switching to PGM mode please refer to 5.2 All remaining line parameters are
immediately effective after programming.
All parameters are not retained by the non-volatile memory before having switched from PGM mode to
RUN mode. If there is no switchover PGM/RUN, in case of power failure the previously programmed
parameters will be applied.
Write -command (standard):
<STX> identifier line P data <ETX> [<CR>]
